Can't upload a background video at my portfolio

Thanks for sharing the name of the template. I will give creating a whole new site with Martias a try. Super annoying, but it it works for being able to handle PAGE BACKGROUND video, then I suppose it will be worth it. Wish Adobe would either fix the issue or simply let users know which templates can handle a simple video background.

Thanks for sharing. Unfortunately changing the template screws up everything one has done in the previous template. That said, what template exactly worked for you? I want to put a video as the page background (not the masthead), but I suppose it's possible switching to whatever template you switched to would solve the same problem as well. 

It's in swedish now, but it says "An error occured. You must refresh the page. Please refresh the page" up in the right corner when I click at "click here to upload a picture/video" and then select a video.
